What is a Business License?

A business license is an annual tax for doing business within the city limits of Martinez. The City Martinez Municipal Code requires that you obtain a license when you conduct any business activity within the City even if your business is located OUTSIDE the city limits or you have a business license from another city. Any business based in the City must have a license as well. This includes home based businesses, building contractors, independent contractors, and non-profit businesses.

Business licenses fees help pay for city services like roads, fire, police and other community services. These services benefit businesses, business owners, and the general public.

In an effort to streamline the business license process the City of Martinez has partnered with HDL to enable online transactions.
